Coffee berry borer in conilon coffee in the Brazilian Cerrado: an ancient pest in a new environment

Abstract

The aim of this study was to verify the occurrence of the coffee berry borer, Hypothenemus hampei (Ferrari), and to evaluate the population fluctuation of the pest in the Brazilian Cerrado (Federal District). The study was conducted, between November 2014 and October 2015, at Embrapa Cerrados (Planaltina/DF, Brazil) in an irrigated conilon coffee production area. In November 2014, 120 samples (ten berries/sample) were collected from berries that had fallen on the ground from the previous harvest. Between November 2014 and October 2015, insects were collected weekly, using traps (polyethylene terephthalate bottles) baited with ethyl alcohol (98 GL), ethyl alcohol (98 GL) with coffee powder, or molasses. Between January and July 2015, samples were collected fortnightly from 92 plants (12 berries per plant). All samples were evaluated for the presence of adult coffee berry borers. Samples from the previous harvest had an attack incidence of 72.4%. The baited traps captured 4062 H. hampei adults, and showed no statistical difference in capture efficiency among the baits. Pest population peaked in the dry season, with the largest percentage of captured adults occurring in July (31.0%). An average of 18.6% of the collected berries was attacked by the borer and the highest percentage incidence was recorded in July (33.2%). Our results suggest that the coffee berry borer, if not properly managed, could constitute a limiting factor for conilon coffee production in the Brazilian Cerrado.

Best time and doses to associate chemical and biological control of the coffee berry borer in highland region, Brazil

“…Surveys carried out in Hawaii showed that the peaks of infestations of flying adults occurred close to the harvest time and coincided with the high infestations of berries; however, a large variation in trapping was found within the same property and among properties, with an increase in infestation level in the second and third generation of CBB (Aristizábal et al, 2017a, b). Similarly, the population of CBB in Brazil is negatively correlated with the intensity of rainfall, and the highest adult populations occur in the dry season (May -August) with population peaks at the end of the harvest season (July -August) (Ferreira et al, 2000;Oliveira et al, 2018;Souza;Reis, 1997). The first spraying of insecticides was carried out within the CBB transit season, ~ 90 days after the main flowering that occurred from October 7 to November 11, 2018 (Figure 3).…”

Incorporating Beauveria bassiana Into an Integrated Pest Management Plan for Coffee Berry Borer in Hawaii

“…Published recommendations for an IPM program designed for the CBB in Hawaii include field monitoring, use of B. bassiana and other insecticides, field sanitation, and post-harvest control (Kawabata et al, 2017;Aristizábal, 2018b). Various IPM strategies for the CBB have been recommended in other regions of the world, including Colombia (Bustillo et al, 1998;Benavides et al, 2002;Aristizábal et al, 2012), Mexico (Barrera et al, 1990), Brazil (Pereira et al, 2012;Olivera et al, 2018), and Africa (Kucel et al, 2009). While an IPM approach is needed, the relatively high cost of field labor in Hawaii remains a limitation for cultural pest control.…”

Estimating the effective sampling area of an alcohol-baited trap for monitoring the coffee berry borer

“…Despite extensive research on the use of these traps for CBB monitoring, consensus remains elusive regarding trap spacing and catch data interpretation, limiting the precision of IPM strategies (Mathieu et al, 1997b;Mathieu et al, 1999;Fernandes et al, 2011;Messing, 2012;Pereira et al, 2012;Aristizábal et al, 2017;Johnson et al, 2018;Oliveira et al, 2018;Souza et al, 2020;Manoukis, 2020, 2021;Ruiz-Diaz and Rodrigues, 2021).…”
